Given numbers are 617, 855, 345, 619

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(617, 855) = 527535

GCD(617, 855) = ( 617 x 855 ) / 527535

= 617 / 855

= 617

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 617, 855, 345, 619 is 1
